Messages from stranger in Whatsapp
Now days it's become a common issue that people are getting Messages from stranger in Whatsapp
It's because, Mobile Number and Profile pictures appears to all members of groups which one is joined
Normally on average if you have 10 groups that means upto 1000 people can see Profile picture and Mobile Number and all these people can contact you
This problem seriously to female whatsapp users, and it can be solved by not putting original Picture and girlish Name
You can also go in SETTINGS => ACCOUNT => PRIVACY => PROFILE PICTURE and change it to Only my Contacts option
But If you want to have your name and picture then even it can be solved by using "Block" option in Whatsapp
Use the Block button which is displayed when you get a message from somebody who is not in your address book
When you block people on WhatsApp, you will no longer receive WhatsApp messages from them.
Blocked contacts don't get "last seen" updates and updates to that contact's profile picture.
Once you block a contact, every time they message you they'll see a single tick, an indication that you haven't read the message.
You can also report to Admin of Group, So Admin can also remove that kinda people who creates problems for others.
